Design of Boost Converter-Inverter with PWAM for Hybrid Vehicle using fuzzy logic controller

Abstract

This paper presents control technique "PWAM" strategy for HEV/EV engine drive framework. This modulation method is quite different from other PWM methods that have been well researched or commonly used for the inverter in HEV/EV system. By using this method, only one phase leg of the inverter is doing switching action for every PWM-carrier period.  The proposed coordinated circuit permits the machine to work in engine mode or goes about as support inductors of the help converter, and along these lines boosting the yield torque coupled to the same transmission framework or dc-link voltage of the inverter associated with the output of the incorporated circuit. In motor mode, the proposed integrated circuit acts as an inverter and it becomes a boost-type boost converter, while using the motor windings as the boost inductors to boost the converter output voltage. A simple fuzzy logic control is built up by a group of rules based on the human knowledge of system behavior .Modeling, analysis, and control of distributed power sources and energy storage devices with MATLAB/ Simulink.
